I have two servers with same 4-core, two threads per core CPUs.

On one, I got coins.

On the other, none.

The difference?

The one getting coins had incoming port open, thus other people's machines had been able to connect to it; it had 75 connections.

The other machine only had 8 connections, the default limit coded into pretty much all the varieties of coins.

I opened its incoming port. I has now, a few minutes later, found a block. It has 25 connections.

(Both are on the same class C subnet, so clients looking for a node to connect to only connect to one of these two machines, as they prefer their connections to be more widely dispersed.)

Oh gosh, if I post this, people might read it. Some might even act on it! That might cut into my share of the coins!

Darn. Okay, lets start a countdown, in only 24 hours I will post this messageadhrfhajfdjdsfgkjmkghm, arg, finger slipped, it posted!

TL;DR please ignore the above, it was posted by mistake!
